To all whom it may concern:

Be it known that I, TITO LIVIO CARBONE, engineer, a citizen of Switzerland, residing at Berlin, Germany, have invented new and useful Im rovements in Clutoh Mechanisms, of which t e following is a specification.

. My invention relates to are lamps the electrode holder of which is suspended by a flexible member such as a chain, a rope or the like passing over a brake wheel, and consists more especially in a regulating mechanism for are lamps of this kind. The action'of the re lating mechanism is an extremely power ul one. It possesses moreover a great sensitiveness, inasmuch as a very small amount of power suffices to bring the brake nto and out of engagement w th the brake wheel.

In order to make me better understood I have shown one particular construction of my new are lamp in the accompanying drawings, in which Figure 1 is a side view of the regulating i 2 is a plan View thereof, sh wing some details in section; Fig. 3 is a si e elevation with the chain wheel in section; 4 is a perspective view of the regulating mechanism; F1gs. 5, 6, 7 show different positions of the re ulating mechanism.

The eleetro e holder 14-is suspended by a chain 15 which passes over the wheel 17 revolvin loosely upon the axle 16. Both ends 0% the latter are fixed in suitable standardsor the like. A tube 23 is also loosely mounted on the fixed axle 16 and has its both ends provided with arms 24-, 25 which form the bearings for an axle 22. In its lowest position the rigid system formed by the tube 23 and its arms 24, 25 rests on a stop 30 rojecting from one of the standards in w rich the axle 16 is fixed. The axle 22 has three arms 21, 27 and 29 rigidly connected with it for instance by screws. The arm 21 is connected by means of a rod 20 with a movable iron core of the electromagnets' 18, 19.

On the arm 27 a brake pad 26 is arranged which 006 crates with the inner surfaces of the rim of t ewheel 17. The arm 29 is connected with the iston rod of a dash pot 28 or of a similar evice which retards the motions of the regulating mechanism.

The operation of the lamp is as follows. If no cin'rent flows through the electrodes and the coils 18, 19 the different parts have the position shown in Fig. 5, the arm 24 resting upon the stop 30 and the pad 26 being only loosely in engagement with the rim of the wheel 17. Upon a current flowing the iron core of the coils 18, 19 is drawn in and turns, by means of the rod 20, the rigid system 21, 22, 27, 29 anti-clockwise, whereby the brake pad 26 is firmly pressed against the rim of the wheel 17 (Fig. 6). As however up to this moment the elec trode holder 14 is not yet lifted, the current further increases, so that the iron core of the coils 18, 19 move still more to theright. The brake pad 26 being pressed against the rim of the wheel 17 the latter is now also turned anti-clockwise, as will be seen from the point marked at the upper part of the wheel 17, and all the parts 23, 2472.5, 27, 21 and 2s rotate a certain angle round 5110 rigid axle 16. Thus the electrode holder Lil lifted by the chain 15 and the tips of the electrodes, which were formerly in contact, are separated from :m other to a certain distance, whereby the or is struck. In conscqucn. .2 ol' the gradual consumption of the electrodes the attraction of the coils 18, 1h diminishes, so that the wheel 14 gradually revolves hack, until the arm 21 comes to rest upon the stop 30. As the wheel 17, however, continues to resolve back, the brake pad 26 comes out ot' engagement with the rim of the wheel 17. Thereupon the electrode holder 14 is allowed to lower, whereby the tips of the electrodes are approached toward one au lhcr, so that the described operation of tlicregul sting mechanism may begin anew.

It is, of course, to be understood. that I do not limit myself to the particular form or the lam shown and described. For instance, the lamp may have electrodes arranged in a straight'line, one above the other. Further the electromagnetic devicemay be provided with only one coil etc.

I claim:

1. In an electric arc lamp the combination with a rcvolublo wheel, a flexible member connected to said wheel an electrode holder suspended by said member, arms rotutably carried by the axle of said'wheel, a revoluble axle mounted in said arms, a stationary stop cooperating with said arms, a brake pad con nectedto said revolublc axle and cooperating with the rim of the wheel, an electro-ning netic device having a core, an arm fixed to the 'revoluble axle and connecting said core with the revoluble axle.

2. In an arc lamp the con'ibination with a revoluble Wheel, a flexible member connected
